This is a repost from February 27, 2013:
I keep getting an Error 1935 when installing Adobe Reader when it gets to about 96% installed. It also says "An error occurred during the installation of assembly component {B708EB72-AA82-3EB7-8BB0-D845BA35C93D}. HRESULT: 0x80073712." I have done everything on the Help page and get the same response. I have reinstalled the .NET Framework, tried turning off the Windows Firewall and antivirus program before installation, run the recommended command at the C: prompt, and tried downloading from the alternative link on the Adobe website. I also ran a registry cleanup utility and still received the same response.
This seems to have been an on-going problem with Adobe Reader for quite some time now, so I hope someone has a fix.
